A source with the inside scoop on the investigation told E! News her sudden death is expected to be officially ruled an accident. She had prescriptions for antidepressants and anti-anxiety medications, and a handful of pill bottles in her hotel room at the Beverly Hilton where she was found deceased.

Official toxicology results haven't been determined yet but her actual cause of death had been temporarily listed as "deferred." That said, "nothing suspicious" was found that would have connected doctors or anyone else to her as a deliberate death.

The potential accident conclusion won't exactly surprise the late Grammy winner's family since they believed her death was accidental in the first place and definitely not due to intentional actions by the fallen star or anyone else around her.

Sounds like the case may be closed very soon. The Beverly Hills Police Department is supposed to get the autopsy tox screen as early as next week.
